I recently switched from Google Chrome to Firefox. I do much accounting work and one nice thing that Chrome did was auto-select full numbers (including commas and decimals) when I double clicked anywhere on the number.
For example, if I double click somewhere on "234" in "$1,234.56" on a page:
- Chrome would auto-select "1,234.56".
- Firefox only auto-selects "234".
Firefox stops at commas and decimal points.
